Unit 102

Key features for navigation include Commissary Ridge running north from LaBarge Creek—a natural backbone that divides drainages and offers glassing vantage points. Fontenelle Mountain and Graham Peak rise as prominent summits visible for miles across open country. The Ham's Fork River and Green River are critical drainages for navigation and water; LaBarge Creek connects them through the unit's heart.

Named gaps (Fontenelle Gap, Rocky Gap, Windy Gap) mark natural passes through ridge systems. Springs—particularly Opal Springs, Jenkins Springs, and Indian Spring—anchor hunter strategy in water-scarce country. Whiskey Basin and Pomeroy Basin are major open expanses that hunters will recognize and use for orientation.

The unit spans medium elevations with a narrow band compressed between roughly 6,100 and 10,300 feet, creating minimal elevation relief for a sprawling area. Lower elevations dominate—mostly open sagebrush flats and grasslands with scattered juniper and low shrub. Timber presence is sparse but concentrated on north-facing slopes and ridge systems like Commissary Ridge, Mahogany Ridge, and Indian Ridge, where ponderosa pine, lodgepole, and aspen appear.

The country is fundamentally high desert with islands of forest rather than forested terrain. Expect long sight lines across open basins, with cover concentrated where drainages cut through ridges and on the shaded aspects of timbered draws.

The unit contains 672 miles of roads, but scattered across vast terrain means access density is low and uneven. I-80 and Highway 30 frame the southern and western approaches; Highway 28 and 372 provide secondary routes. Main roads penetrate toward Fontenelle and up key drainages, but large portions of the unit remain distant from major corridors.

This creates a mixed-pressure environment: accessible ridges and basin edges near established roads draw typical hunting traffic, while the broken terrain between drainages offers solitude for hunters willing to navigate complexity. The terrain complexity score of 7.2 reflects how easy it is to get turned around in the maze of similar basins and ridges.

Unit 102 occupies the upper Green River drainage between Interstate 80 on the south and the Ham's Fork River on the north, spanning roughly from Little America east toward Fontenelle. The western boundary follows Wyoming Highway 372, while the eastern edge traces the Green River itself. The unit sits at the transition between the high desert and the mountains—a broad, complex landscape with multiple ridges, basins, and drainages that funnel through what locals recognize as Pomeroy Basin, Whiskey Basin, and Fontenelle Basin.

Several small towns (Diamondville, Fontenelle, Frontier) ring the perimeter, making access straightforward from multiple directions despite the sparse road network within the unit proper.

Water is limited and scattered, making every spring and reliable creek essential. The Green River forms the eastern boundary with consistent flow; the Ham's Fork River drains the northwest. Interior drainages include Dempsey Creek, Beaver Creek, Hams Fork Creek, and Sheep Creek—most run seasonal or intermittent depending on snowpack and time of year.

Springs cluster in predictable zones: Opal Springs near the southern benches, Jenkins Springs higher in the ridges, Indian Spring in the central draws. Fontenelle Lakes, Twin Creek Lakes, and Mud Lakes provide small water sources but may be seasonal. Craven Creek Reservoir and Graham Reservoir hold water but access depends on private land.

The scarcity of reliable water defines hunting movement and strategy throughout the unit.

Elk are the primary species—this is mid-elevation elk country where animals winter low in the basins and migrate to timbered ridges as snow recedes. Early season hunting targets high ridges with scattered timber like Commissary Ridge and Mahogany Ridge; glassing open basins during morning hours can locate bulls using transition zones. Rut hunting focuses on timbered draws and creek bottoms where cover is thickest.

Late season pushes animals down toward lower sagebrush benches and riparian zones along the Green River and Ham's Fork. Water strategy is critical—hunt springs and creek bottoms in dry periods, as elk concentrate there. Understand that most accessible road approaches will see pressure; success favors hunters exploring the broken country between named drainages where terrain complexity discourages foot traffic.
